To aZZ whom it mcty concern: Fig. 8 is a back view of a portion of the valve Be it known that I, FRANCIS EUGENE A, showing asidewise bearing-roll G and two ADAMS, of Boston, county of Sufiolk, and pressure-bearing rolls D and two wedges C.

In other words, when one roll is rollertrack E and guide K also having a passingaroll-rest most of the others are bearrollertrack E, and between these two tracks ing on the track. When the valve arrives at 5 and body J and guide K, on which they are the seat, the rollers rolldown into the rests mounted, the roller D is inclosed, having conand cease to act, allowing the valve to come tact with either track, according to the dito its seat. During its travel it is held at a rection of pressure upon the valve. One of slight remove from its seat by the rollers the locking wedges C is here also shown. mounted on the track, to which position it is 1 50 These look the valve to its seat when closed. lifted by the rollers when it begins its travel in consequence of the rollers rolling out of the rests so mounting the track. The side- Wise rollers G serve to guide the valve with little or no friction and may be journaled to the valve orits guide K. The guide or track upon which they roll may oppose them on either guide or valve accordingly, and so also of the lifting-rollers. They may be journaled to either the valve or the valve guide or frame and be opposed on either by their track located accordingly. At the same time that the rollers roll down into the roll-rests the Wedges O, which look the valve to its seat, are sliding under their bearings.

In the gate illustrated two hook-Wedges C are shown at the top, two direct Wedges O at the bottom, and four direct wedges upon each side, also marked 0.

It will be observed, the valve being seated as shown in Figs. 2 and 3, that on its being moved in the direction foropening, as seen by arrow in Fig. 2, the rollsD begin to roll up out of their rests, so lifting the valve fromcontact with its seat; also, that on the return movement the rollers support the valve free and out of contact with its seat until on nearing and reaching the closing-point the supporting-rollers roll into the roller-rests and the valve comes to its seat.

The invention may be applied to all fluidgates, large or small, but is of the most and of very great importance in the case of large gates and heavy pressures. They may be constructed of the usual or any suitable material.

I claim- 1. The combination in a fluid-gate of a flatfaced valve and stem made to move in a direction parallel to the valve-face and a flatfaced frame or body having a fluid-way transverse to its face, said frame and valve being provided with grooved tread and journaled, rollers,upon one,and correspondiugly-shaped roller-tracks having roller rests or depressions on the other, said grooved rollers roller-tracks and roller-rests all arranged and operating together substantially in the manner and for the purpose set forth.

2. The combination of the flat-faced valve, a valve-lifting stem, the flat-faced frame or body having a transverse fluid way or passage the one being provided with journaled rollers and the other with roller-tracks along the sides of the valve and fluid way or passage, to act upon each other in a direction corresponding to the fluid-pressure and with similar rolls upon one and tracks upon the other to act sidewise on each side of the Valve in a direction parallel to the valves face, said journaled rollers and tracks, all substantially as shown and described and for the purpose set forth.

3. The combination in a fluid-gate of a valve having a flat face, a series of supporting-rollers journaled upon its sides, a set of guiding-rollers also journaled upon the valve and acting laterally upon the valve-guides,

the roller-tracks, a frame or body supporting said guides, and tracks at the sides of the valve to bear the said lifting-rollers, all substantially as and for the purpose set forth.

4. The combination of the flat-faced valve, a valve-stem, the flat-faced frame or body and the side guides inclosing the rollers, the two tracks therein allowing the rollers to act either way according to the direction of pressure in the line of the fluid-way, all substantially as shown and described for the purpose set, forth.

5. The combination in a fluid-gate of the flat-faced valve, its operatingstem, the flatfaced frame or body having a transverse fluidway, a set of supporting-rollers and rollertracks upon the frame, having roller rests or depressions, a set of laterally-acting guides rollersand the side guides upon which they act, all operating together substantially as and for the purpose set forth.

6. In a fluid-gate the combination of the valve having a fiat face, and operating-stem, the frame, also having a fiat face or valveseat, a transverse fluid way or passage within the valve-seat, the rollers constructed with a grooved tread, the correspondingly-shaped roller-track fitting said rollers and the rollerrests formed in said track at points coincident with the location of said rollers near and at the closing-point in the valves travel, all substantially as shown and described and for the purpose set forth.

7. The combination in afluid-gate of the valve-supportin g rollers, the tracks which resist the fluid pressure and flow, in the ordinary direction, and those which resist any reverse or backward flow or pressure, the frame, guides and valve, said rollers having action upon their respective tracks according to the direction of the usual, or anybackward, flow, substantially as shown and described.

8. In a fluid-gate having a flat-faced valve and a frame or body having a flat valve-seat around a transverse fluid way or passage, the combination of said valve, its stem, seat and frame, a set of rollers and tracks at each side of the valve and its fluid-way, acting ina direction transverse to the fluid-way to guide the valve, another set of valve and pressure rollers acting to lift the valve out of contact with its seat by means of the valves travel and the roller-rests to receive the rolls so allowing the valve to be seated, all substantially as shown and described and for the purpose set forth.

9. In a fluid-gate having a flat-faced valve and seat, the seat-bearing frame having a fluid way or passage through the frame Within said valve-seat, the construction of said valve with a projecting roller-track on each side with roller rests therein, substantially as shown and described.

10. In a fluid-gate having a flat-faced valve and a frame or body having a flat face or valve-seat and a fluid-way or through-passage within said valveseat, the combination of side guiding and valve-supporting rolls and roll-rests, substantially as shown and described. p

11. In afluid-gate having a flat-faced valve, a frame or body having a flat valve-seat and a fluid way or passage within said valve-seat, the combination of the valve-supporting rollers journaled on two sides of the valve, the

valve, valve-stem, and the two guides and frame or body constituting two roller-containing ways, with the two opposing roller-tracks frame or body having a flat valve-seat inclosupon which the rollers act in opposite directions according to the direction of pressure upon the valve, all substantially as shown and described, and for the purpose set forth.

12. In a fluid-gate the combination of a ing the fluid way or passage and a fiat-faced valve seated thereon, the double or opposing FRANCIS EUGENE ADAMS.
